Comment:
The Standard Class successor to the LS-1, the LS-
4 first flew in 1980. It features a new airfoil
(Wortmann mod.) on its double-tapered wing,
larger upper-surface double segment Schempp-
Hirth type airbrakes and a variety of rigging
improvements. The fuselage is derived from that
of the LS-3a. The improved LS-4a has an
increased gross weight and ballast capacity and
strengtened landing gear. LS-4ﾒs took the first
6 places (and 21 out of the first 25) in the
Standard Class at the 1983 World Championships
at Hobbs, NM. |
